The SE-4 module is the pre-calibrated replacement sensor used for the C-21 VOC Monitor.
The sensor (SE-4) is a serviceable part on the C-21 and it's a good practice to replace it annually. When the C-21 is no longer responding to gases and vapors, it's likely due to sensor failure and must be replaced.
The C-21 is broadly sensitive to most VOCs, but its response is different for each one. To calibrate for a specific gas, a chemical laboratory is required. To view this procedure see Tech Note C-100.
SE-4 VOC Sensor Replacement:
Sensor replacement on C-21 is simply plug-n-play. Remove the old SE-4 sensor and replace with the new one.
